Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a spring with greater elastic force is adopted to bear the weight of the all-in-one computer and force the cam member to generate automatic rotation, then the automatic engaging function is improved, but the supporter rapidly rotates and engages automatically when no weight is applied, causing accidents and safety hazards
Solution Approach 1:
A viscous damping member is introduced as an intermediary component between the cam member and the rotation shaft. This damping member generates viscous resistance that opposes the elastic force of the spring, thereby controlling the rotation speed of the supporter and preventing rapid accidental engagement while maintaining the automatic engaging function.
Solution Approach 2:
The patent replaces the purely mechanical spring-driven rotation system with a system that incorporates viscous damping. The viscous damping force, which depends on the rotation speed, substitutes for uncontrolled mechanical elastic force, providing smooth and controlled automatic engagement without sudden rapid movement.
2Extent of automation
If a spring with greater elastic force is used to ensure automatic rotation, then the automatic engaging effect is enhanced, but the supporter rotates rapidly without weight application, causing collision and danger
Solution Approach 1:
The viscous damping member serves as a mediator that introduces controlled resistance between the cam member and rotation shaft. This resistance counteracts the harmful rapid rotation effect while preserving the beneficial automatic rotation function, thereby eliminating collision and danger hazards.
Solution Approach 2:
The patent changes the dynamic parameters of the rotation system by introducing viscous damping force, which varies with rotation speed. This parameter change transforms the system from high-speed rapid rotation to controlled slow rotation, eliminating harmful collisions while maintaining automatic engagement.
3Ease of operation
If the supporter is designed to rotate and engage automatically, then the ease of operation is improved, but the rapid engagement causes safety hazards and reduces reliability
Solution Approach 1:
The viscous damping member is introduced as an intermediary that modifies the engagement characteristics. It maintains the ease of operation by preserving automatic engagement while improving reliability by preventing rapid movement and potential safety hazards through controlled viscous resistance.
